HI All,

My 2014 Z51 Coupe (Auto,3LT) has experienced 3 episodes that begin with stabilitrac warning light, followed by many others, loss of dash gauges, loss of Air Conditioning, cruise control and items such as door locks. Shutting down and restarting does not clear the problem, although the chassis items seem to perform better, the AC and Cruise does not return.
First failure required about 15 minute cooldown before would restart, and produced 12 pages of codes basically covering every module. Codes were cleared and printout provided to dealer. Computer modules under rear tray were 150 degrees per infrared thermometer. 1 week later nothing found.
Issue recurred while driving car home from dealer....at less than 25 mph. computer modules didn't "feel" as hot as first episode, and Vehicle towed to dealer. Now, after 17 days at the dealer, there is still no solution.
Needless to say, my patience is exhausted, and I am preparing to pursue the Lemon Law resolution process.

Purpose of my post:
Heads up to the group in hopes someone has an idea for diagnosis.
Thoughts on best approach to lemon law process. (the vehicle has met the requirements to file. Only thing left is to send a certified letter to GM and give them 1 final shot).
Hoping for GM to speak up.

Thanks for reading. Sorry for the long post.
